Hi, probably an out of nowhere message for a mod you made 3 years ago. But before I get into specifics just wanna preface that I love the mod, best of the CC item refits I've seen and if I'mma be honest probably the best refit of the official Bethesda released sets. Now into the problem I've been having that I'm not quite sure on the cause of, for 5 of the armors, their nail textures are missing on the hands, those armors being the 3 Spell Knight sets, the Steel Soldier, and the Daedric Mail. Wraithguard is also having an issue that's a lot weirder, in third person the texture is perfectly fine, but in first person it completely breaks, I've tested with just SAM Light installed, as well as with the high poly conversion and the texture add-on, problem persists in both (to show this the Daedric Mail screenshot is from my main save where I'm using all 3 mods listed, the rest are from a clean save with several less mods installed, I've also included my installed mods to show all I have when testing. spoiler tagged for the sake of keeping this post being really long. This occurs equally between man races, mer races, and beast races.
Don't mind the BHUNP stuff that's there for testing a different texture error, funnily enough also for the Spell Knight trio (guess it's just feeling buggy for me), I've tested both with and without them installed and the missing nail textures persists, screenshot just happens to be taken from while I had them ticked on.
Will also state that I've tried with both only the meshes and with the bodyslide files ticked.
